130973-44-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130973-44-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,9,7 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 130973-44:
(8*1)+(7*3)+(6*0)+(5*9)+(4*7)+(3*3)+(2*4)+(1*4)=123
123 % 10 = 3
So 130973-44-3 is a valid CAS Registry Number.

Asymmetric metal-catalysed epoxidation of electron-deficient olefins
Bailey,Staton,Ashton,Marko,Ollis
, p. 495 - 509 (2007/10/02)
The SYN diastereospecific epoxidation of acyclic β-hydroxyketones (β-hydroxyacrylates) and cyclic β-hydroxyketones using titanium and vanadium catalysts is reported. Some initial results on the asymmetric epoxidation of these systems using the Sharpless t
